Exercise stepper

Abstract

An exercise stepper has a bottom rack, two treadle bars, an inclined bar, a handle, a supporting rod and two oil pressure cylinders. Wherein the front ends of the two treadle bars are pivotally connected to two end spots of the front axle shaft. The treadle bars have on the front sections thereof connecting areas for connecting the two oil pressure cylinders; the rear ends of the treadle bars are extended rearwardly to form treadle pedals. The inclined bar is pivotally connected on the bottom end thereof with the rear end of the bottom rack, the front end thereof is extended frontwardly and upwardly, the upper end has a function display meter, a connecting area for the handle is provided on the upper end of the inclined bar being slip jointed with the handle. The supporting rod is horizontally extended through a neck portion of the inclined bar. The oil pressure cylinders are connected on the upper ends thereof to the supporting rod, and are connected on the lower ends thereof to the connecting areas for the oil pressure cylinders. Thereby, when a treadle pedal is trampled down, the other treadle pedal is relatively subjected to a force and is lifted, and vice versa, the exercise stepper thus is formed. The structure with the connecting areas for the oil pressure cylinders, for the handle and for the inclined bar etc. can have the components thereof collapsed onto the bottom rack.

1 . An exercise stepper comprises: 
 a bottom rack provided with a front axle shaft, a rear bar and an intermediate bar connecting to the middle of said front axle shaft and the middle of said rear bar;    two treadle bars, the front ends of said two treadle bars are pivotally connected to a right and a left spot respectively aside of said middle of said front axle shaft, the rear ends of said treadle bars are extended rearwardly to form treadle pedals; said treadle bars are adapted to rotating up or down in relation to said front axle shaft for an angle, and are provided on the front sections thereof with connecting areas for connecting with two oil pressure cylinders;    an inclined bar, being pivotally connected on the bottom end thereof with a connecting area in said middle of said rear bar, the front end thereof is extended frontwardly and upwardly, the upper end thereof is provided with a function display meter;    a handle slip jointed with a connecting area for said handle which is connected to the rear side on said upper end of said inclined bar;    a supporting rod horizontally extended through a neck portion of said inclined bar; and    two oil pressure cylinders, connected on the upper ends thereof to said supporting rod, and connected on the lower ends thereof to connecting areas for said two oil pressure cylinders respectively;    with the above stated structure, when one of said treadle pedals is trampled down, the other of said treadle pedals is relatively subjected to a force and is lifted, and vice versa, said exercise stepper thus is formed; said structure, in which the bottoms of said two oil pressure cylinders are pivotally connected with said connecting areas for said oil pressure cylinders in front of said two treadle bars, said handle is slip jointed with said connecting area for said handle, and said inclined bar is pivotally connected on the bottom end thereof with a connecting area of said rear bar, allows components thereof collapsed onto said bottom rack thereof.    
     
     
         2 . The exercise stepper as in  claim 1 , wherein 
 said bottom rack is in the shape of “H”, said rear bar is in the shape of a stable elliptic bar not subjected to sliding, the two ends of said elliptic rear bar are provided each with a roller.    
     
     
         3 . The exercise stepper as in  claim 1 , wherein 
 the front axle shaft of said bottom rack has in the middle thereof a cushion block.    
     
     
         4 . The exercise stepper as in  claim 1 , wherein 
 said front axle shaft connected with the ends of said treadle bars are provided on the two ends thereof each with an annular fixing member.
